SPIROL Expands Press-In Insert Line with the Introduction of Aluminium
SPIROL is pleased to introduce a range of 2024 aluminium Press-In Inserts. Available in symmetrical (Series INS 50) and headed (INS 51) versions, the new aluminium Press-In Inserts complements the existing brass line. Threaded Inserts are essential for reinforcing plastic components and provide a reusable thread within a bolted assembly. This ensures a proper seating torque and prevents the potential for plastic creep over time that could otherwise compromise the performance of the assembly.
SPIROL’s Inserts are designed to optimize both performance and cost, and are available in a variety of options tailored for different performance requirements and installation methods. Inserts designed to be Pressed-In without heat, such as SPIROL’s INS 50 and INS 51, are intended to provide the lowest cost to install with acceptable joint performance for many applications.
While brass remains the industry standard for machining due to its material properties, 2024 aluminium offers distinct lightweight advantages at 1/3rd the weight. This 2024 aluminium grade is lead-free, addressing evolving environmental health and safety concerns associated with lead content in machined products. Additionally, the distinct galvanic properties between aluminum and brass provide a broader spectrum of options, catering to diverse application needs.
The function and total overall cost of the assembly vary drastically based on the type of Insert used in the application. SPIROL’s Engineering team will help determine the most appropriate Insert based on the specific application and assembly requirements.
